  What is the meaning of LED Lamp color temperature?

  The color temperature is the scale of the light color of the light source, in units of K (Kelvin)!

  In physics, color temperature refers to a standard black body heating, the temperature rises to a certain extent, the color begins to be dark red - light red - orange - white - blue, gradually change, a light source and black body color, we will The absolute temperature at the time of the blackbody is called the color temperature of the light source. Color temperature is in the photography, video, publishing and other fields have important applications! Color temperature warm white, natural white (white), cool white and so on.

  LED Lamp color temperature is LED Lamps when the color, generally divided into warm white (2700K-4500K), white (4500-6500K), cool white (6500K above) three.

  Usually the light seen by the human eye is composed of seven kinds of shades of light. But some of them light blue, some are reddish, color temperature is designed to measure and calculate the color composition of light method. How to accurately color-temperature positioning? This requires the use of the "color temperature meter". Under normal circumstances, noon from 10 pm to 2 pm, sunny sky, in the absence of direct sunlight, the standard daylight at about 5200 ~ 5500 ° K. The color temperature of the news light is 3200 ° K; the general tungsten filament, the studio photo shoots the black and white photographs using the tungsten filament light and the ordinary ordinary light bulb has a color temperature of about 2800 ° K; the color temperature is low, so in this case Photo taken after the print out will feel yellow color. And the general fluorescent lamp color temperature in the 7200 ~ 8500 ° K or so, so the photos taken under the fluorescent light will be partial blue.
